Questão jurídica principal
Whether the continued pretrial detention was justified by a concrete risk of collusion.
Decisão extraída
Yes. The pending investigations and contacts with persons who might incriminate the accused made the collusion risk concrete and plausible.
Fundamentação extraída
A mere abstract collusion risk is insufficient, but here further investigative steps remained, including hearings of persons contacted from prison and inquiries involving related third parties; the accused did not effectively rebut these findings.
